[spoiler][/spoiler]As you can read from the scan above it says the following:
Those who quote the above page use it as “proof” that Goku travelled half a planet is one second or so. Now the thing is that this page from this Shonen Jump is actually wrong (or mistranslated it doesn't matter). The statement that Goku was at the other side of the planet is 100% false.As Freeza changes into new forms each more powerful than the last, the desperate heroes […] find themselves struggling to merely stay alive. […] On the other side of the planet Goku awakens from within his healing capsule and streaks to the battle field to turn the tide.
Goku in chapter 290 (after his body received severe damage from the fight of Ginuy-Goku versus Vegeta) was put into a healing chamber. This was in Freeza’s spaceship. And … the battles against Freeza happened NEAR the spaceship, not at the other side of the planet. For those that forgot the exact story, while Goku was healing in the spaceship, Vegeta took a nap outside the spaceship. Meanwhile Kuririn went to learn the incantation for the Dragonballs and upon his return to the spaceship together with Dende he shout to Gohan and altogether they took the Dragonballs (which were outside the spaceship), and went a little bit away (to not awake Vegeta) and summoned Porunga. But where they went was very close to the spaceship. And we know this for a fact because when Vegeta woke up he could see Porunga summoned a very short distance away from where he was at (which was at the spaceship). And because a picture equals one thousand words…from chapter 293:
When Vegeta realised that Kuririn and Gohan summoned the dragon in secret, he became angry, he went there and had an argument with them and since there was still one wish left and Freeza was approaching, they agreed to let him wish for immortality. But then the great Elder died, Porunga disappeared and the Dragonballs turned into stones. Vegeta got mad about not getting his wish, started shouting at Kuririn but Freeza showed up.
All the subsequent battles against Freeza happened there/nearby. They didn’t move to a different place or to the other side of the planet in order to fight. Sure enough they might have moved a little during fighting, like 100-200m or so, but definitely they didn't go to the other side of the planet. So when Goku healed up and travelled from the spaceship to the battlefield the distance he travelled was like 500m or so – certainly NOT half a planet’s circumference (… unless Namek was super-small like Kaio’s planet which we know for a fact it wasn’t).
